Adam Scott, bidding to become just the second man in more than two decades to win the Masters in back-to-back years, kicks off his title defense in the company of Jason Dufner and Matthew Fitzpatrick.

Scott, who downed Angel Cabrera in a second playoff hole in 2013, and Dufner share at least one thing in common: They won their opening majors last year. In Scott's case, it ended years of near misses at golf's biggest events.

The famously laid-back Dufner -- "Dufnering" is a phenomenon -- captured the PGA Championship about four months after Scott became the first Australian to wear the famous green jacket and 19-year-old Fitzpatrick has earned a reputation, too.

Last August he became the first Englishman to claim the U.S. Amateur Championship in more than 100 years.
